  2. Introduction Getting to Know Computers

  3. Q1. What is a Computer • Answer: • A computer is an electronic device that manipulates information, or "data.“ • It has the ability to store, retrieve, and process data. • You can use a computer to type documents, send email, and browse the internet. • You can also use it to handle spreadsheets, accounting, database management, presentations, games, and more.

  4. Types of Computers 1. Desktop Computers 2.Laptop Computers 3.Tablet Computers

  5. Desktop Computers • Many people use desktop computers at work, home, school, or the library. They can be small, medium, or large in style, and usually sit on a desk. Once you add a monitor, mouse, and a keyboard, you have what is typically known as a desktop computer. • Most desktop computers are easy to upgrade and expand, or add new parts. Another benefit of desktop computers is the cost. If you compare a desktop and a laptop with the same features, you will most likely find that the desktop computer is priced lower. • Some desktop computers have a built-in monitor to save space. These are often called all-in-one desktop computers.

  6. Laptop Computers • The second type of computer that you may be familiar with is a laptop computer, or laptops as they are often referred to. Laptops are battery or AC-powered personal computers that are more portable than desktop computers, allowing you to use them almost anywhere. • Since a laptop is smaller than a desktop, it's more difficult to access the internal components. That means you may not be able to upgrade them as much as a desktop. However, it's usually possible to add more RAM or a bigger hard drive. • A laptop computer is sometimes called a notebook computer because of its size.

  7. Tablet Computers • A tablet computer, or simply tablet, is a one-piece mobile computer. • It has a touchscreen, with finger or stylus gestures replacing the computer mouse. It is often supplemented by physical buttons or input from sensors such as accelerometers. • An on-screen, hideable virtual keyboard is usually used for typing. Tablets differentiate themselves by being larger than smart phones or personal digital assistants. They are usually 7 inches (18 cm) or larger, measured diagonally • Though generally self-contained, a tablet computer may be connected to a physical keyboard or other input device. A number of Hybrids that have detachable keyboards have been sold since the mid-1990s. Convertible touchscreen notebook computers have an integrated keyboard that can be hidden by a swivel or slide joint. Booklet tablets have dual-touchscreens and can be used as a notebook by displaying a virtual keyboard on one of the displays.

  8. Other Types of Computers • Mobile Phones: Many mobile phones can do a lot of things a computer can do, such as browsing the internet or playing games. These phones are often called smartphones. • Game Consoles: A game console is a specialized kind of computer that is used for playing video games. Although they are not as fully-featured as a desktop computer, many newer consoles, such as the Nintendo Wii, allow you to do non-gaming tasks like browsing the internet. • TVs: Many TVs now include applications (or apps) that let you access various types of online content. For example, you can view your Facebook news feed or watch streaming movies on Netflix.

  9. Types of Desktop computers PC Computer Mac Computers • PC: This type of computer began with the original IBM PC that was introduced in 1981. Other companies began to create similar computers, which were called IBM PC Compatible (often shortened to PC). Today, this is the most common type of personal computer, and it typically includes the Microsoft Windows operating system. • Although PC can refer to an IBM PC Compatible, the term can also be used to refer to any personal computer, including Macs. • Mac: The Macintosh computer was introduced in 1984, and it was the first widely sold personal computer with a Graphical User Interface, or GUI (pronounced gooey). All Macs are made by one company, Apple Inc., and they almost always use the Mac OS X operating system.
